R8C/32A Group 2. Central Processing Unit (CPU) 2.1 Data Registers (R0, R1, R2, and R3) R0 is a 16-bit register for transfer, arithmetic, and logic operations. The same applies to R1 to R3. R0 can be split into high-order bits (R0H) and low-order bits (R0L) to be used separately as 8-bit data registers. R1H and R1L are analogous to R0H and R0L. R2 can be combined with R0 and used as a 32-bit data register (R2R0). R3R1 is analogous to R2R0. 2.2 Address Registers (A0 and A1) A0 is a 16-bit register for address register indirect addressing and address register relative addressing. It is also used for transfer, arithmetic, and logic operations. A1 is analogous to A0. A1 can be combined with A0 and as a 32bit address register (A1A0). 2.3 Frame Base Register (FB) FB is a 16-bit register for FB relative addressing. 2.4 Interrupt Table Register (INTB) INTB is a 20-bit register that indicates the starting address of an interrupt vector table. 2.5 Program Counter (PC) PC is 20 bits wide and indicates the address of the next instruction to be executed. 2.6 User Stack Pointer (USP) and Interrupt Stack Pointer (ISP) The stack pointers (SP), USP and ISP, are each 16 bits wide. The U flag of FLG is used to switch between USP and ISP. 2.7 Static Base Register (SB) SB is a 16-bit register for SB relative addressing. 2.8 Flag Register (FLG) FLG is an 11-bit register indicating the CPU state. 2.8.1 Carry Flag (C) The C flag retains carry, borrow, or shift-out bits that have been generated by the arithmetic and logic unit. 2.8.2 Debug Flag (D) The D flag is for debugging only. Set it to 0. 2.8.3 Zero Flag (Z) The Z flag is set to 1 when an arithmetic operation results in 0; otherwise to 0. 2.8.4 Sign Flag (S) The S flag is set to 1 when an arithmetic operation results in a negative value; otherwise to 0. 2.8.5 Register Bank Select Flag (B) Register bank 0 is selected when the B flag is 0. Register bank 1 is selected when this flag is set to 1. 2.8.6 Overflow Flag (O) The O flag is set to 1 when an operation results in an overflow; otherwise to 0.

VCC = 2.7 to 5.5 V at Topr = 0 to 60°C, unless otherwise specified. 2. Definition of programming/erasure endurance The programming and erasure endurance is defined on a per-block basis. If the programming and erasure endurance is n (n = 100 or 10,000), each block can be erased n times. For example, if 1,024 1-byte writes are performed to block A, a 1 Kbyte block, and then the block is erased, the programming/erasure endurance still stands at one. However, the same address must not be programmed more than once per erase operation (overwriting prohibited). 3. Endurance to guarantee all electrical characteristics after program and erase. (1 to Min. value can be guaranteed). 4. In a system that executes multiple programming operations, the actual erasure count can be reduced by writing to sequential addresses in turn so that as much of the block as possible is used up before performing an erase operation. For example, when programming groups of 16 bytes, the effective number of rewrites can be minimized by programming up to 128 groups before erasing them all in one operation. It is also advisable to retain data on the erase count of each block and limit the number of erase operations to a certain number. 5. If an error occurs during block erase, attempt to execute the clear status register command, then execute the block erase command at least three times until the erase error does not occur. 6. Customers desiring program/erase failure rate information should contact their Renesas technical support representative. 7. The data hold time includes time that the power supply is off or the clock is not supplied. 8. The erase sequence does not proceed unless the interval of 20 ms or more is allowed from when an erase operation starts/restarts until the following suspend is requested.
